The Mystery of the Appearing Shopping

Yesterday morning I opened my curtains just before 9am, to find that someone had left two full carrier bags tucked just inside our garden wall. We investigated, and found food from Waitrose, new saucepans and other kitchen equipment. It had rained the night before, and they weren't wet, but at least the food must have come from Cheltenham, not here.

Baffled, we left the bags out, assuming their owner would come back for them, but no sign so far, they are still there.

Someone could, I suppose, have got off the early bus, struggled bringing them up the hill and left them for later, but you'd think they would have been back for them within 24 hours...
